* Updated DRBD->get_next_resource() to take the new 'dr_tcp_ports' ports which, if set, returns two free TCP ports.

Browse Source 
* Got anvil-manage-dr to the point where it writes the updated resource configuration to enable DR support. (untexted)

This is the Anvil! in which we're looking for the next free resources. It's required, but generally it doesn't need to be specified as we can find it via C<< Cluster->get_anvil_uuid() >>.
=head3 dr_tcp_ports (optional, default '0')
If set, the 'free_port' returned will be a comma-separated pair of TCP ports. This is meant to help find two TCP ports needed to connect a resource from both nodes to a DR host.
=head3 resource_name (optional)
If this is set, and the resource is found to already exist, the first DRBD minor number and first used TCP port are returned. Alternatively, if C<< force_unique >> is set to C<< 1 >>, and the resource is found to exist, empty strings are returned.
